To all whom it may concern.'

Be it known that I, JAMES A. LANSING, u citizen of thev United States, residing at Scranton, in the 'county of Laclniwanna and State of'Pennsylvnnizi, have invented certain new and useful improvements in Do Inestic Ranges; and l do hereby declare the .following to be a full, clear, and exact description of the ssa-nie, reference being had to the accompanying drawings, forming part of this specification, and to the figures and letters of reference marken thereon.

The object of the present invention is to .provide n domestic range adapted prinirv rily 'for cooking purposes with the use of gaseous fuel combined with a. water hen-ting arrangement adapted to be heated either by the consumption of gaseous fuel or solid fuel, to which ends the range embodiesl r. water buck, or coil'through which water circulated from an ordinary domestic heilen one side of seid waiter back being exposed to a combustion chamber adapted for the burning of solid fuel of any ordinary kind such as coalV or Wood tnd the other side exposed to .e coihustion chamber in .which gaseous fuel is burned, there beingr iin ,ar` rangement of ldempers whereby the econoinicnlandfsae operation of either the gaseous fuelburners vor of the combustion Chamber for 'solid fuel may be effec-ted without being interfered with by the construction adapted for use in connection Awithxth e burner or combustion chamber which islfor the time being .not in'nse. 4

The innention further contemplates :i domeetic, range in which the oven or portion.

of the range adapted for baking and the portion of the range adapted for cooking;`

' with ordinary exposed utensils may be util ized without being interfered with oy the 'water heating and 'solid udl burning por tions of the range, all of sriyid parts being embodied in a simpleorganized :irrange ment adapted for utilization by domestic help without particular inechzuiinl knowledge er high mental ability.

Above vthefoven 105 i space B in which theusul'top nu located. These burners ere they univ lie beneath nsolid or beneath n grating top lr, y type. iiue F2 for cnr- No u tion from the comb tween the ton of Athe oven and pan or floor below burner C.A

It has an opening F, and the space above the oven in which the burners C are located has an opening F. Bot-h of said o enings lead into a flue box G located at the ack of .the range and through which communication 1s had with a stove pipe or smoke stack connection The flue box G extends along the back of the range, and the fire pot I communicates therewith through an o ening z', best seen in elevationrin Fig. 1. n the oven side the fire box may have the usual fire brick lining k and the fuel is supported by a grate such as the Dockash grate K illustrated. On the opposite side of the fire box from the fire brick lining lc, said box is defined by a water back L through which Water is circulated from an ordinary d0- mestic boiler shown in dotted lines at S through ipe connections indicated at l in Fig. 3. n the side ofthe water back away from the fire bpx a combustion chamber for gaseous fuel is formed, which combustion chamber is entirely independent of the fire box and its ash pit, so that dust will not be liable to find its way into the same. This combustion chamber is preferably defined by the removable end wall M of the range in Fig. l, which conveniently is the inner wall of a door M having slide damper controlled openings m therein preferably at top and bottom, through which air is admitted to the lower part of the combustion chamber a considerable distance below the water back. .The door fits an opening in the permanent end wall M2 of the range structure. The chamber on the gas burner side of the waterback'communicates with the Hue box at the rear of the stove through an openingl N, and between the several openings in the Hue box the box is provided with y dampers whereby the passage of products through it may be arrested at will. As shown in the drawings, dampers O and O are pivotally mounted at their lower edges in the Hue box so as to turn up into position for closing the box or down into position for permitting the free passage of products therethrough, and for operating said dampers, the usual damper rods o, o extend, out to the front of the range, where they are readily accessible and the dampersmay be opened or closed at will depending upon which of the combustion chambers is to be utilized for generating heat. Various arrangements of t'he flue box' and dampers will at once occur to those familiar with the art of range construction, and in Fig. 4 an arrangement is illustrated in which, instead of the damper O in the flue box for closing communication with the gas burner side of the Water heater, a long pivoted damper is provided at O2 which controls a correspondingly shaped opening between the lire box and chamber, whereby the products of combustion from the/gas burner side of the fire box may be permitted to pass into the top of the fire box and thence into the flue box, or when the' fire box is used exclusively, said damper may be closed and the admission of air above v the fuel prevented. A long damper, such as O2, may be combined with the flue box damper O, and this is the preferred arrangement, as shown in Figs. 1 and 6, where the long damper is indicated by the reference letter O3. The arrangement is such that when one is open the other is closed, and vice versa. When the long damper O3 is opened the heated products of',

combustion from the gas burner chamber are sent through the upper portion of the fire box to the flue box and stack connections, and this arrangement is desirable inasmuch as it permits of the utilization of such heated products for the purpose of drying out or incinerating garbage, etc., which may be placed in the lire box in a suitable receptacle, without the necessity of building a fire in the fire box.

In a range embod ing a water heater adapted to be heate by either solidr or gaseous fuel combustion, great diiculty has been experienced in devising an arrangement which would heat the water by the combustion of gaseous fuel in a reasonable time, and to a suflicient degree, which fact probably accounts for the failure of devices of this character to be more generally used. After a long series of experiments I have ascertained that with an arrangement such as illustrated wherein a series of superposed gas burners are employed located mainly below the bottom level of the water heater and the flue so arranged that adequate oxygen is supplied to the several superposed burners, and a large volume of heated air caused to sweep over the water heater, the heating operation by use of gaseous fuel may be successfully and economically accomplished. By reference to the rawings it will be vseen that three long gas burners R, R and R2 are arranged in the chamber, two' of said burners being located below the bottom level of the water back and the other of said burners being located lower portion of the outer face o said water back. From the latter burner the flame impin es directly against the surface of the water acl: and from the lower burners the flame is directed toward that sidcof the chamber on which the water back is located, so that the effect of the heat and llame is to heat the water back on the side and bottom as well as the metal immediately adjacent and in conductive relation thereto. With this arrangement the burners receive' an adequate supply of oxygen, and one does no. interfere with the operation of the other. The burners are preferably independently controlled as are all opposite the.

sov

being so arranged with relation to each other, that when one is opened the other is closed, and vice versa.

In a domestic range, the combination with an oven, a fire box for the consumption of solid fuel, a Water back at 011e side of said fire box and a gas burner chamber von the side of said water back away from the fire box and in immediate proximity thereto, of a flue box at the rear of the range for carrying off the products from the oven, re box and gas burner chamber, and a pivoted damper having wings arranged at an that when one is in closed position the other 20 is in open position, and vice versa.
